JAMES F. HOTGHKISS, OF PLAINFIELD, NEW JERSEY. V

BOILER-CLEANER.

SPECIFICATION forming part of Letters Patent No. 276,410, dated April 24, 1883.

Application mea March 10,1883. (No model.)

To all whom it may concern:

Be it known thatv I, J AMES F. HorcHKIss,

p of Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in .Boiler Cleaners, of which the following is a specification.

My invention has reference to that class of cleaners in which the scum or impurities thrown to the surl'ace of` the water by ebullition are received into a funnel connected with a'pipe leading to a depositing-tank; and it consists in improvements in the construction ot' the tunnel and its pipe-connection, as hereinafter specified.

1n the accompanying drawings, Figure l is a perspective view of the invention. Fig. 2 is a longitudinal section thereof. Fig. 3 is a transverse section upon the line x o t Fig. 2.

Similar letters of reference indicate similar partsin the respective figures.

A is the-hub or support for the funnel B. The support Ais made otcast-iron, and in the form of a frustum of a cone, the Wider portion extending upward at an angle, and receiving the apex or small end of the conical sheet-iron funnel B.l The latter is attached to the support A by rivets a or equivalent devices. The small or lower end ofthe support A unites with a part, b, cast therewith, and

standing in a horizontal line, its axis being' that of the connecting-pipe or screW-thimble c. The thimble .c attaches to the pipe into which the water of the boiler first flows on its passage to the sediment collector or tank..

The portion of the part b which immediately f adjoins the small end ofthe support Ais pref'- erably of hexagonal or other polygonal lortu, the remainder being circular, except at the top `and bottom, where it is Hat-sided, the said flat surfaces being, as shown,contiuuatious ofthe upper and lower sides of the hexagon. The bore of the part b is circular, terminating at its inner end at a shoulder, d. A shortv vertical pin, e, preferrbly cast with the part b, is

placed near its outer end, and engages with a slot, f, cut in the pipe or screw-thimble c. A

`set-screw tc .is tapped into the opposite side ofxthe hexagon and secures the support A and its funnel to the pipe or screw-thmble c.

The object of the pin e, slotted p ipe or thimble c, and set-screw c is to effect a certain lirst placed. The use of the pin e and slotf 6o renders it impossible for the funnel to be placed in any' but the true position. By making the funnel with a cast support or hub and a sheet-iron extension the device may be readily inserted within any boiler. `The support or hub, being ot' comparatively small size, can be put through any small opening of the boileras a hand-hole, Stdand the sheetiron extension may be atened and inserted, and then again given its shape and attached to the support or hub by screws, it' desired.

I claim as my inventionl. A funnel and pipe-connection for the purpose described, consisting of a funnel-support or hub having a pipe bore or aperture, and a xed pin or projection, combined with a slotted pipe, substantially' as set forth.

2. In a funnel `and pipe-connection for the purpose described, a funnel-support` or hub having a pipe bore or aperture, and a fixed pin or projection extending within `the same, combined with a slotted screwthimble or pipe and a set-screw, substantially as set forth.
